I'm going to invest in a GTX 780. I have complete custom watercooling installed, which I'm going to hook it up to (for overclocking ofc.)

I see Asus has a stock version and a OC'ed version. Do they both, theoretically (I know there are good and bad chips) have the same overclocking potential ?
I obviously don't care about the coolers they've put on, so is this the only difference ? Apart from them turning up the speeds from the factory ofc. That's what I'm going to do myself with MSI Afterburning for example...

Bottom line - Is there any idea in buying an OC version, when I'm going to watercool and OC it myself. Or can I save the money and get the same out of a stock version...?
